FIELD OF THE DISCLOSURE

The present disclosure relates to compositions intended for human use.The compositions are configured for oral use and deliver substances suchas flavors and/or active ingredients during use. Such products mayinclude tobacco or a product derived from tobacco, or may betobacco-free alternatives.

BACKGROUND

Tobacco may be enjoyed in a so-called “smokeless” form. Particularlypopular smokeless tobacco products are employed by inserting some formof processed tobacco or tobacco-containing formulation into the mouth ofthe user. Conventional formats for such smokeless tobacco productsinclude moist snuff, snus, and chewing tobacco, which are typicallyformed almost entirely of particulate, granular, or shredded tobacco,and which are either portioned by the user or presented to the user inindividual portions, such as in single-use pouches or sachets. Othertraditional forms of smokeless products include compressed oragglomerated forms, such as plugs, tablets, or pellets. Alternativeproduct formats, such as tobacco-containing gums and mixtures of tobaccowith other plant materials, are also known. See for example, the typesof smokeless tobacco formulations, ingredients, and processingmethodologies set forth in U.S. Pat. No. 1,376,586 to Schwartz; U.S.Pat. No. 4,513,756 to Pittman et al.; U.S. Pat. No. 4,528,993 toSensabaugh, Jr. et al.; 4,624,269 to Story et al.; U.S. Pat. No.4,991,599 to Tibbetts; U.S. Pat.

These and other features, aspects, and advantages of the disclosure willbe apparent from a reading of the following detailed descriptiontogether with the accompanying drawings, which are briefly describedbelow. The invention includes any combination of two, three, four, ormore of the above-noted embodiments as well as combinations of any two,three, four, or more features or elements set forth in this disclosure,regardless of whether such features or elements are expressly combinedin a specific embodiment description herein. This disclosure is intendedto be read holistically such that any separable features or elements ofthe disclosed invention, in any of its various aspects and embodiments,should be viewed as intended to be combinable unless the context clearlydictates otherwise.

BRIEF DESCRIPTION OF THE DRAWINGS

Having thus described aspects of the disclosure in the foregoing generalterms, reference will now be made to the accompanying drawings, whichare not necessarily drawn to scale. The drawings are exemplary only, andshould not be construed as limiting the disclosure.

FIG. 1 is a perspective view of a pouched product embodiment, takenacross the width of the product, showing an outer pouch filled with acomposition of the present disclosure.

DETAILED DESCRIPTION

The present disclosure will now be described more fully hereinafter withreference to example embodiments thereof. These example embodiments aredescribed so that this disclosure will be thorough and complete, andwill fully convey the scope of the disclosure to those skilled in theart. Indeed, the disclosure may be embodied in many different forms andshould not be construed as limited to the embodiments set forth herein;rather, these embodiments are provided so that this disclosure willsatisfy applicable legal requirements. As used in this specification andthe claims, the singular forms “a,” “an,” and “the” include pluralreferents unless the context clearly dictates otherwise. Reference to“dry weight percent” or “dry weight basis” refers to weight on the basisof dry ingredients (i.e., all ingredients except water). Reference to“wet weight” refers to the weight of the composition including water.Unless otherwise indicated, reference to “weight percent” of acomposition reflects the total wet weight of the composition (i.e.,including water).

The products as described herein comprise one or more fillers, and atleast one additional component selected from the group consisting ofactive ingredients, flavorants, and combinations thereof. The relativeamounts of the various components within the composition may vary, andtypically are selected so as to provide the desired sensory andperformance characteristics to the oral product. In certain embodiments,the oral products of the present disclosure are characterized by reduceddensity as compared to certain commercial products, which can provideboth manufacturing and storage/transport cost savings, as well asimproved environmental impact metrics generated from the lower weight,such as improved life cycle assessment (LCA)/reduced CO₂ footprint. Theexample individual components of the composition are described hereinbelow.

Filler

Compositions as described herein include at least one filler. Suchfillers may fulfill multiple functions, such as enhancing certainorganoleptic properties such as texture and mouthfeel, enhancingcohesiveness or compressibility of the product, and the like. Generally,the fillers are particulate materials and/or fibrous materials, and arecellulose-based. For example, suitable fillers are any non-tobacco plantmaterial or derivative thereof, including cellulose materials derivedfrom such sources. Examples of cellulosic non-tobacco plant materialinclude cereal grains (e.g., maize, oat, barley, rye, buckwheat, and thelike), sugar beet (e.g., FIBREX® brand filler available fromInternational Fiber Corporation), bran fiber, bamboo fiber, wood pulpfiber, cotton fiber, citrus pulp fiber, grass fiber, willow fiber,poplar fiber, cocoa fiber, derivatives thereof, and mixtures thereof.Non-limiting examples of derivatives of non-tobacco plant materialinclude starches (e.g., from potato, rye, oat, barley, wheat, rice,corn), natural cellulose, and modified cellulosic materials. Additionalexamples of potential fillers include maltodextrin, dextrose, calciumcarbonate, calcium phosphate, lactose, mannitol, xylitol, and sorbitol.As described in more detail below, combinations of fillers can also beused. Note that many of the above plant sources for filler materials canbe used in a variety of forms, including processed plant material in theform of particulates or fibers, or in relatively unprocessed forms(e.g., whole straw) such as straw materials from common grains such asrye, wheat, oat, or barley.

“Starch” as used herein may refer to pure starch from any source,modified starch, or starch derivatives. Starch is present, typically ingranular form, in almost all green plants and in various types of planttissues and organs (e.g., seeds, leaves, rhizomes, roots, tubers,shoots, fruits, grains, and stems). Starch can vary in composition, aswell as in granular shape and size. Often, starch from different sourceshas different chemical and physical characteristics. A specific starchcan be selected for inclusion in the composition based on the ability ofthe starch material to impart a specific organoleptic property tocomposition. Starches derived from various sources can be used. Forexample, major sources of starch include cereal grains (e.g., rice,wheat, and maize) and root vegetables (e.g., potatoes and cassava).Other examples of sources of starch include acorns, arrowroot,arracacha, bananas, barley, beans (e.g., favas, lentils, mung beans,peas, chickpeas), breadfruit, buckwheat, canna, chestnuts, colacasia,katakuri, kudzu, malanga, millet, oats, oca, Polynesian arrowroot, sago,sorghum, sweet potato, quinoa, rye, tapioca, taro, tobacco, waterchestnuts, and yams. Certain starches are modified starches. A modifiedstarch has undergone one or more structural modifications, oftendesigned to alter its high heat properties. Some starches have beendeveloped by genetic modifications, and are considered to be “modified”starches. Other starches are obtained and subsequently modified. Forexample, modified starches can be starches that have been subjected tochemical reactions, such as esterification, etherification, oxidation,depolymerization (thinning) by acid catalysis or oxidation in thepresence of base, bleaching, transglycosylation and depolymerization(e.g., dextrinization in the presence of a catalyst), cross-linking,enzyme treatment, acetylation, hydroxypropylation, and/or partialhydrolysis. Other starches are modified by heat treatments, such aspregelatinization, dextrinization, and/or cold water swelling processes.Certain modified starches include monostarch phosphate, distarchglycerol, distarch phosphate esterified with sodium trimetaphosphate,phosphate distarch phosphate, acetylated distarch phosphate, starchacetate esterified with acetic anhydride, starch acetate esterified withvinyl acetate, acetylated distarch adipate, acetylated distarchglycerol, hydroxypropyl starch, hydroxypropyl distarch glycerol, andstarch sodium octenyl succinate.

Filler materials characterized by a relatively low density, particularlyfiller materials derived from certain plant sources, can be used inproducts of the present disclosure. Such materials are typicallyutilized in either a particulate or fibrous form. For example, productsof the present disclosure can include non-tobacco cellulosic materialsselected from the group consisting of maize, oat, barley, rye,buckwheat, sugar beet, bran, bamboo, wood pulp, cotton, citrus pulp,grass, willow, poplar, cocoa, derivatives thereof, and combinationsthereof. Such materials often have an untapped bulk density of about 150g/L or less, about 125 g/L or less, about 100 g/L or less, about 75 g/Lor less, or about 50 g/L or less. In some embodiments, such materialshave an untapped bulk density in the range of about 50 g/L to about 150g/L, or about 50 g/L to about 125 g/L, or about 75 g/L to about 100 g/L.In one embodiment, the relatively low density plant-based fillercomprises bamboo. Such bamboo materials are available from, for example,MIKRO-TECHNIK GmbH & Co. KG or ID FOOD.

The low density filler component can form part of a blend of fillers orcan comprise the entire filler content of the oral product. In certainembodiments, it has been found that using a combination of fillers canprovide a product with a reduced weight without compromising sensory(e.g., taste, feel, etc.) characteristics of the oral product. Reducingthe weight of the oral product can provide benefits such as lowermaterial transport costs. Without intending to be limited by theory, ithas been found that the weight of oral products of the presentdisclosure can be decreased by (i) at least partially replacing arelatively high density filler material with a lower density fillermaterial; and/or (ii) at least partially replacing a particulate fillermaterial with a fibrous filler material. The use of filler materialshaving a relatively low density reduces overall weight of a product unitof a given volumetric size. In addition, use of a filler material havingthe form of a fiber, as opposed to particulate, provides an increase inthe bulking impact of the filler material, which also reduces overallweight for a product unit of a given volumetric size.

In some embodiments, the oral products of the present disclosurecomprise a combination of fillers. The combination of fillers caninclude a first filler material and a second filler material, whereinthe first filler material has a higher bulk density than the secondfiller material. In certain embodiments, the first filler material hasan untapped bulk density of about 250 g/L or higher, about 300 g/L orhigher, about 350 g/L or higher, about 400 g/L or higher, about 500 g/Lor higher, or about 750 g/L or higher. In some embodiments, the firstfiller material has a bulk density in the range of about 250 g/L toabout 1200 g/L, about 250 g/L to about 600 g/L, about 250 g/L to about400 g/L, or about 250 g/L to about 350 g/L. In various embodiments, thesecond filler material (e.g., a plant-based cellulosic material such asbamboo) has a bulk density of about 150 g/L or less, about 125 g/L orless, about 100 g/L or less, about 75 g/L or less, or about 50 g/L orless. In some embodiments, such materials have an untapped bulk densityin the range of about 50 g/L to about 150 g/L, or about 50 g/L to about125 g/L, or about 75 g/L to about 100 g/L.

In various embodiments, the oral products described herein can include afirst filler material in particulate form and a second filler materialin fibrous form. In some embodiments, both the first filler material andthe second filler material can be in particulate form. In certainembodiments, both the first filler material and the second fillermaterial can be fibrous materials.

In some embodiments, the first filler material is a cellulose materialor a cellulose derivative. In various embodiments, the first fillermaterial is a non-tobacco cellulosic material. One particularly suitablefirst filler for use in the products described herein ismicrocrystalline cellulose (“MCC”). The MCC may be synthetic orsemi-synthetic, or it may be obtained entirely from natural celluloses.The MCC may be selected from the group consisting of AVICEL® gradesPH-100, PH-102, PH-103, PH-105, PH-112, PH-113, PH-200, PH-300, PH-302,VIVACEL® grades 101, 102, 12, 20 and EMOCEL® grades 50M and 90M, and thelike, and mixtures thereof. In various embodiments, the MCC is aparticulate material having an average particle size in the range ofabout 25 to about 800 microns, about 50 microns to about 250 microns,about 75 microns to about 150 microns, or about 90 microns to about 100microns.

In certain embodiments, the first, high-density filler material can bepresent in an amount of about 1% by weight to about 96% by weight, about10% by weight to about 94% by weight, about 25% by weight to about 90%by weight, about 50% by weight to about 85% by weight, based on thetotal weight of fillers in the oral product. In some embodiments, thefirst, high-density filler material can be present in an amount of about25% or higher, about 50% or higher, about 75% or higher, about 85% orhigher, or about 90% or higher, based on the total weight of fillers inthe oral product.

In various embodiments, the oral products described herein can include asecond, low-density filler material, wherein the second filler materialis a cellulose material or a cellulose derivative. In variousembodiments, the second filler material is a non-tobacco cellulosicmaterial. In some embodiments, the second filler material is a fibrousmaterial selected from the group consisting of maize fiber, oat fiber,barley fiber, rye fiber, buckwheat fiber, sugar beet fiber, bran fiber,bamboo fiber, wood pulp fiber, cotton fiber, citrus pulp fiber, grassfiber, willow fiber, poplar fiber, cocoa fiber, derivatives thereof, andcombinations thereof. One particularly suitable second filler for use inthe products described herein is bamboo fibers.

In some embodiments, the second filler material is a low-density (ascompared to a first filler material) cellulosic material in particulateor fibrous form. For example, in various embodiments, the second fillermaterial is a bamboo material. In various embodiments, the bamboomaterial has an average particle size in the range of about 25 micronsto about 800 microns, about 30 microns to about 200 microns, or about 30microns to about 100 microns. In various embodiments, the bambooparticulate material has a particle size of about 25 microns or greater,about 30 microns or greater, about 50 microns or greater, or about 75microns or greater.

In certain embodiments, the second, low-density filler material can bepresent in an amount of about 4% by weight to about 99% by weight, about6% by weight to about 90% by weight, about 10% by weight to about 75% byweight, or about 15% by weight to about 50% by weight, based on thetotal weight of fillers in the oral product. In some embodiments, thesecond, low-density filler material can be present in an amount of about4% or higher, about 6% or higher, about 10% or higher, about 12% orhigher, or about 15% or higher, based on the total weight of fillers inthe oral product. In certain embodiments, the oral products of thepresent disclosure include only a single low-density filler material, ora combination of two or more low-density filler materials. For example,in some embodiments, the filler material is 100 weight percent of abamboo material, based on the total weight of the filler within the oralproduct.

The total amount of filler(s) can vary, but is typically greater thanabout 20%, and up to about 75% of the composition by weight, based onthe total weight of the composition. A typical range of filler (e.g.,bamboo fiber alone or MCC in combination with bamboo fibers) within thecomposition can be from about 20 to about 75% by total weight of thecomposition, for example, from about 20, about 25, or about 30, to about35, about 40, about 45, or about 50% by weight (e.g., about 20 to about50%, or about 25 to about 45% by weight). In certain embodiments, theamount of filler is at least about 20% by weight, such as at least about25%, or at least about 30%, or at least about 35%, or at least about40%, based on the total weight of the composition. In certainembodiments, the amount of low-density filler component within thecomposition is about 2% or higher, about 3% or higher, about 4% orhigher, or about 5% or higher, based on the total weight of thecomposition.

In some embodiments, the products of the disclosure can be characterizedas completely free or substantially free of additional fillers otherthan the above-noted high-density and low-density filler materials. Forexample, certain embodiments can be characterized as having less than 1%by weight, or less than 0.5% by weight, or less than 0.1% by weight ofadditional fillers, or 0% by weight of additional fillers. In otherembodiments, the products of the disclosure can be characterized ascompletely free or substantially free of additional fillers other thanthe above-noted low-density filler materials. For example, certainembodiments can be characterized as having less than 1% by weight, orless than 0.5% by weight, or less than 0.1% by weight of additionalfillers, or 0% by weight of additional fillers, other than theabove-noted low-density filler materials.

Bleached Active Ingredient

In some embodiments, the oral product comprises an active ingredient asdisclosed herein, wherein the active ingredient is characterized asbleached. Such a bleached active ingredient may be desirable e.g., toprevent tooth discoloration during use of the oral product, or so thatany residue remaining in the mouth of the user after use of the productis less visible, and is less likely to cause staining of fibrousmaterials, such as clothing, that may contact the residue. By “bleached”active ingredient is meant an active ingredient (e.g., a botanicalmaterial or derivative thereof), which, in its natural state possesses acolor, and which has been treated to reduce or eliminate the color. By“color” is meant the characteristic of human visual perception describedthrough color categories, with names such as red, blue, yellow (primarycolors) or brown, orange, green, purple, and the like, resulting fromcombinations of primary colors. This perception of color derives fromthe stimulation of cone cells in the human eye by electromagneticradiation in the visible spectrum, associated with objects through thewavelength of the light that is reflected from them. This reflection isgoverned by the object's physical properties such as e.g., absorptionand emission spectra across the electromagnetic spectrum.

Certain active ingredients, by virtue of naturally occurring chemicalcompounds therein which reflect light in the visible range of theelectromagnetic spectrum, impart a color to the active ingredient (e.g.,chlorophyll or pigment decomposition products in certain botanicalmaterials, responsible for green color and brown colors, respectively).Such chemical compounds, or a portion thereof, which are responsible forthe color of the active ingredient, may be chemically altered or removedby various treatments. In some embodiments, the treatment is effectiveto eliminate at least 70% of the chemicals present in the activeingredient having maximum transmission of wavelengths in the visiblerange of the electromagnetic spectrum, based on the weight of thenaturally occurring compounds. For example, such treatment may beeffective to remove 70%, 80%, 90%, 95%, 99%, or even 100% of thenaturally occurring compounds responsible for the visible color of theactive ingredient.

In some embodiments, the treatment for bleaching (i.e., altering orremoving colored chemical compounds from the active ingredient) includesextraction, chemical bleaching, or a combination thereof. Oneparticularly suitable extraction method is supercritical carbon dioxide(CO₂) extraction. Methods of chemical bleaching of e.g., botanicalmaterials, including tobacco, are known, and include as non-limitingexamples, treatment with hydrogen peroxide, ozone, or other oxidizingagents. For example, bleached active ingredients (e.g., a bleachedbotanical or tobacco material) may be produced by various whiteningmethods using various bleaching or oxidizing agents.

See also, Leffingwell et al., Tobacco Flavoringfor Smoking Products, R. J. Reynolds Tobacco Company (1972), which isincorporated herein by reference. Flavoring agents also may includecomponents that are considered moistening, cooling or smootheningagents, such as eucalyptus. These flavors may be provided neat (i.e.,alone) or in a composite, and may be employed as concentrates or flavorpackages (e.g., spearmint and menthol, orange and cinnamon; lime,pineapple, and the like). Representative types of components also areset forth in U.S. Pat. No. 5,387,416 to White et al.; US Pat. App. Pub.No. 2005/0244521 to Strickland et al.; and PCT Application Pub. No. WO05/041699 to Quinter et al., each of which is incorporated herein byreference. In some instances, the flavoring agent may be provided in aspray-dried form or a liquid form.

Taste Modifiers

In order to improve the organoleptic properties of a composition asdisclosed herein, the composition may include one or more tastemodifying agents (“taste modifiers”) which may serve to mask, alter,block, or improve e.g., the flavor of a composition as described herein.Non-limiting examples of such taste modifiers include analgesic oranesthetic herbs, spices, and flavors which produce a perceived cooling(e.g., menthol, eucalyptus, mint), warming (e.g., cinnamon), or painful(e.g., capsaicin) sensation. Certain taste modifiers fall into more thanone overlapping category.

In some embodiments, the taste modifier modifies one or more of bitter,sweet, salty, or sour tastes. In some embodiments, the taste modifiertargets pain receptors. In some embodiments, the composition comprisesan active ingredient having a bitter taste, and a taste modifier whichmasks or blocks the perception of the bitter taste. In some embodiments,the taste modifier is a substance which targets pain receptors (e.g.,vanilloid receptors) in the user's mouth to mask e.g., a bitter taste ofanother component (e.g., an active ingredient). In some embodiments, thetaste modifier is capsaicin.

In some embodiments, the taste modifier is the amino acid gamma-aminobutyric acid (GABA), referenced herein above with respect to aminoacids. Studies in mice suggest that GABA may serve function(s) in tastebuds in addition to synaptic inhibition. See, e.g., Dvoryanchikov etal., J Neurosci. 2011 Apr. 13; 31(15):5782-91. Without wishing to bebound by theory, GABA may suppress the perception of certain tastes,such as bitterness. In some embodiments, the composition comprisescaffeine and GABA.

In some embodiments, the taste modifier is adenosine monophosphate(AMP). AMP is a naturally occurring nucleotide substance which can blockbitter food flavors or enhance sweetness. It does not directly alter thebitter flavor, but may alter human perception of “bitter” by blockingthe associated receptor.

In some embodiments, the taste modifier is lactisole. Lactisole is anantagonist of sweet taste receptors. Temporarily blocking sweetnessreceptors may accentuate e.g., savory notes.

When present, a representative amount of taste modifier is about 0.01%by weight or more, about 0.1% by weight or more, or about 1.0% by weightor more, but will typically make up less than about 10% by weight of thetotal weight of the composition, (e.g., from about 0.01%, about 0.05%,about 0.1%, or about 0.5%, to about 1%, about 5%, or about 10% by weightof the total weight of the composition).

In a still further aspect is provided a method for modifying the flavorprofile of an active ingredient in a composition, the compositioncomprising a filler in an amount of at least 20%, based on the totalweight of the composition; at least one active ingredient comprising oneor more botanical materials, stimulants, amino acids, vitamins,antioxidants, nicotine components, cannabinoids, pharmaceutical agents,or a combination thereof; a salt; and at least one sweetener; whereinthe product composition has a moisture content of at least about 40% byweight, based on the total weight of the composition; wherein the methodcomprises providing a taste modifier in the product composition in anamount effective to mask or modify a taste sensation in the mouth of theuser of the composition. In some embodiments, the taste modifierselected from the group consisting of an analgesic or anesthetic herb,spice, or flavor which produces a perceived cooling or warming effect,gamma-aminobutyric acid, capsaicin, and adenosine monophosphate. In someembodiments, the taste sensation is bitterness, sweetness, saltiness, orsourness. In some embodiments, the taste sensation is bitterness. Insome embodiments, the taste modifier is capsaicin.

Descriptions of various types oftobaccos, growing practices and harvesting practices are set forth inTobacco Production, Chemistry and Technology, Davis et al. (Eds.)(1999), which is incorporated herein by reference.

Nicotiana species from which suitable tobacco materials can be obtainedcan be derived using genetic-modification or crossbreeding techniques(e.g., tobacco plants can be genetically engineered or crossbred toincrease or decrease production of components, characteristics orattributes). See, for example, the types of genetic modifications ofplants set forth in U.S. Pat. No. 5,539,093 to Fitzmaurice et al.; U.S.Pat. No. 5,668,295 to Wahab et al.; U.S. Pat. No. 5,705,624 toFitzmaurice et al.; U.S. Pat. No. 5,844,119 to Weigl; U.S. Pat. No.6,730,832 to Dominguez et al.; U.S. Pat. No. 7,173,170 to Liu et al.;U.S. Pat.

See, also, the types of tobaccos thatare set forth in U.S. Pat. No. 4,660,577 to Sensabaugh, Jr. et al.;5,387,416 to White et al.; and 6,730,832 to Dominguez et al., each ofwhich is incorporated herein by reference.

The Nicotiana species can, in some embodiments, be selected for thecontent of various compounds that are present therein. For example,plants can be selected on the basis that those plants produce relativelyhigh quantities of one or more of the compounds desired to be isolatedtherefrom. In certain embodiments, plants of the Nicotiana species(e.g., Galpao commun tobacco) are specifically grown for their abundanceof leaf surface compounds. Tobacco plants can be grown in greenhouses,growth chambers, or outdoors in fields, or grown hydroponically.

Various parts or portions of the plant of the Nicotiana species can beincluded within a composition as disclosed herein. For example,virtually all of the plant (e.g., the whole plant) can be harvested, andemployed as such. Alternatively, various parts or pieces of the plantcan be harvested or separated for further use after harvest. Forexample, the flower, leaves, stem, stalk, roots, seeds, and variouscombinations thereof, can be isolated for further use or treatment. Insome embodiments, the tobacco material comprises tobacco leaf (lamina).The composition disclosed herein can include processed tobacco parts orpieces, cured and aged tobacco in essentially natural lamina and/or stemform, a tobacco extract, extracted tobacco pulp (e.g., using water as asolvent), or a mixture of the foregoing (e.g., a mixture that combinesextracted tobacco pulp with granulated cured and aged natural tobaccolamina).

In certain embodiments, the tobacco material comprises solid tobaccomaterial selected from the group consisting of lamina and stems. Thetobacco that is used for the mixture most preferably includes tobaccolamina, or a tobacco lamina and stem mixture (of which at least aportion is smoke-treated). Portions of the tobaccos within the mixturemay have processed forms, such as processed tobacco stems (e.g.,cut-rolled stems, cut-rolled-expanded stems or cut-puffed stems), orvolume expanded tobacco (e.g., puffed tobacco, such as dry ice expandedtobacco (DIET)). See, for example, the tobacco expansion processes setforth in U.S. Pat. No. 4,340,073 to de la Burde et al.; U.S. Pat. No.5,259,403 to Guy et al.; and 5,908,032 to Poindexter, et al.; and7,556,047 to Poindexter, et al., all of which are incorporated byreference. In addition, the d mixture optionally may incorporate tobaccothat has been fermented. See, also, the types of tobacco processingtechniques set forth in PCT WO2005/063060 to Atchley et al., which isincorporated herein by reference.

The tobacco material is typically used in a form that can be describedas particulate (i.e., shredded, ground, granulated, or powder form). Themanner by which the tobacco material is provided in a finely divided orpowder type of form may vary. Preferably, plant parts or pieces arecomminuted, ground or pulverized into a particulate form using equipmentand techniques for grinding, milling, or the like. Most preferably, theplant material is relatively dry in form during grinding or milling,using equipment such as hammer mills, cutter heads, air control mills,or the like. For example, tobacco parts or pieces may be ground ormilled when the moisture content thereof is less than about 15% byweight, or less than about % by weight. Most preferably, the tobaccomaterial is employed in the form of parts or pieces that have an averageparticle size between 1.4 millimeters and 250 microns. In someinstances, the tobacco particles may be sized to pass through a screenmesh to obtain the particle size range required. If desired, airclassification equipment may be used to ensure that small sized tobaccoparticles of the desired sizes, or range of sizes, may be collected. Ifdesired, differently sized pieces of granulated tobacco may be mixedtogether.

The manner by which the tobacco is provided in a finely divided orpowder type of form may vary. Preferably, tobacco parts or pieces arecomminuted, ground or pulverized into a powder type of form usingequipment and techniques for grinding, milling, or the like. Mostpreferably, the tobacco is relatively dry in form during grinding ormilling, using equipment such as hammer mills, cutter heads, air controlmills, or the like. For example, tobacco parts or pieces may be groundor milled when the moisture content thereof is less than about 15% byweight to less than about 5% by weight. For example, the tobacco plantor portion thereof can be separated into individual parts or pieces(e.g., the leaves can be removed from the stems, and/or the stems andleaves can be removed from the stalk). The harvested plant or individualparts or pieces can be further subdivided into parts or pieces (e.g.,the leaves can be shredded, cut, comminuted, pulverized, milled orground into pieces or parts that can be characterized as filler-typepieces, granules, particulates or fine powders). The plant, or partsthereof, can be subjected to external forces or pressure (e.g., by beingpressed or subjected to roll treatment). When carrying out suchprocessing conditions, the plant or portion thereof can have a moisturecontent that approximates its natural moisture content (e.g., itsmoisture content immediately upon harvest), a moisture content achievedby adding moisture to the plant or portion thereof, or a moisturecontent that results from the drying of the plant or portion thereof.For example, powdered, pulverized, ground or milled pieces of plants orportions thereof can have moisture contents of less than about 25% byweight, often less than about 20%, and frequently less than about 15% byweight.

For the preparation of oral products, it is typical for a harvestedplant of the Nicotiana species to be subjected to a curing process. Thetobacco materials incorporated within the mixture for inclusion withinproducts as disclosed herein are those that have been appropriatelycured and/or aged. Descriptions of various types of curing processes forvarious types of tobaccos are set forth in Tobacco Production, Chemistryand Technology, Davis et al. (Eds.) (1999). Examples of techniques andconditions for curing flue-cured tobacco are set forth in Nestor et al.,Beitrage Tabakforsch. Int., 20, 467-475 (2003) and U.S. Pat. No.6,895,974 to Peele, which are incorporated herein by reference.Representative techniques and conditions for air curing tobacco are setforth in U.S. Pat. No. 7,650,892 to Groves et al.; Roton et al.,Beitrage Tabakforsch. Int., 21, 305-320 (2005) and Staaf et al.,Beitrage Tabakforsch. Int., 21, 321-330 (2005), which are incorporatedherein by reference. Certain types of tobaccos can be subjected toalternative types of curing processes, such as fire curing or suncuring.

In certain embodiments, tobacco materials that can be employed includeflue-cured or Virginia (e.g., K326), burley, sun-cured (e.g., IndianKurnool and Oriental tobaccos, including Katerini, Prelip, Komotini,Xanthi and Yambol tobaccos), Maryland, dark, dark-fired, dark air cured(e.g., Madole, Passanda, Cubano, Jatin and Bezuki tobaccos), light aircured (e.g., North Wisconsin and Galpao tobaccos), Indian air cured, RedRussian and Rustica tobaccos, as well as various other rare or specialtytobaccos and various blends of any of the foregoing tobaccos.

The tobacco material may also have a so-called “blended” form. Forexample, the tobacco material may include a mixture of parts or piecesof flue-cured, burley (e.g., Malawi burley tobacco) and Orientaltobaccos (e.g., as tobacco composed of, or derived from, tobacco lamina,or a mixture of tobacco lamina and tobacco stem). For example, arepresentative blend may incorporate about 30 to about 70 parts burleytobacco (e.g., lamina, or lamina and stem), and about 30 to about 70parts flue cured tobacco (e.g., stem, lamina, or lamina and stem) on adry weight basis. Other example tobacco blends incorporate about 75parts flue-cured tobacco, about 15 parts burley tobacco, and about 10parts Oriental tobacco; or about 65 parts flue-cured tobacco, about 25parts burley tobacco, and about 10 parts Oriental tobacco; or about 65parts flue-cured tobacco, about 10 parts burley tobacco, and about 25parts Oriental tobacco; on a dry weight basis. Other example tobaccoblends incorporate about 20 to about 30 parts Oriental tobacco and about70 to about 80 parts flue-cured tobacco on a dry weight basis.

Tobacco materials used in the present disclosure can be subjected to,for example, fermentation, bleaching, and the like. If desired, thetobacco materials can be, for example, irradiated, pasteurized, orotherwise subjected to controlled heat treatment. Such treatmentprocesses are detailed, for example, in U.S. Pat. No. 8,061,362 to Muaet al., which is incorporated herein by reference. In certainembodiments, tobacco materials can be treated with water and an additivecapable of inhibiting reaction of asparagine to form acrylamide uponheating of the tobacco material (e.g., an additive selected from thegroup consisting of lysine, glycine, histidine, alanine, methionine,cysteine, glutamic acid, aspartic acid, proline, phenylalanine, valine,arginine, compositions incorporating di- and trivalent cations,asparaginase, certain non-reducing saccharides, certain reducing agents,phenolic compounds, certain compounds having at least one free thiolgroup or functionality, oxidizing agents, oxidation catalysts, naturalplant extracts (e.g., rosemary extract), and combinations thereof. See,for example, the types of treatment processes described in U.S. Pat.Nos. 8,434,496, 8,944,072, and 8,991,403 to Chen et al., which are allincorporated herein by reference. In certain embodiments, this type oftreatment is useful where the original tobacco material is subjected toheat in the processes previously described.

In various embodiments, the tobacco material can be treated to extract asoluble component of the tobacco material therefrom. “Tobacco extract”as used herein refers to the isolated components of a tobacco materialthat are extracted from solid tobacco pulp by a solvent that is broughtinto contact with the tobacco material in an extraction process. Variousextraction techniques of tobacco materials can be used to provide atobacco extract and tobacco solid material. See, for example, theextraction processes described in US Pat. Appl. Pub. No. 2011/0247640 toBeeson et al., which is incorporated herein by reference. Other exampletechniques for extracting components of tobacco are described in U.S.Pat. No. 4,144,895 to Fiore; U.S. Pat.

In some embodiments, the type of tobacco material is selected such thatit is initially visually lighter in color than other tobacco materialsto some degree (e.g., whitened or bleached). Tobacco pulp can bewhitened in certain embodiments according to any means known in the art,and as described above in reference to color-eliminated activeingredients.

Typical inclusion ranges for tobacco materials can vary depending on thenature and type of the tobacco material, and the intended effect on thefinal composition, with an example range of up to about 30% by weight(or up to about 20% by weight or up to about 10% by weight or up toabout 5% by weight), based on total weight of the composition (e.g.,about 0.1 to about 15% by weight). In some embodiments, the products ofthe disclosure can be characterized as completely free or substantiallyfree of tobacco material (other than purified nicotine as an activeingredient). For example, certain embodiments can be characterized ashaving less than 1% by weight, or less than 0.5% by weight, or less than0.1% by weight of tobacco material, or 0% by weight of tobacco material.

Preparation of the Composition

The manner by which the various components of the composition (e.g.,filler, water, active ingredient, and the like) are combined may vary.As such, the overall composition with e.g., powdered compositioncomponents may be relatively uniform in nature. The components notedabove, which may be in liquid or dry solid form, can be admixed in apretreatment step prior to mixture with any remaining components of thecomposition, or simply mixed together with all other liquid or dryingredients. The various components of the composition may be contacted,combined, or mixed together using any mixing technique or equipmentknown in the art. Any mixing method that brings the compositioningredients into intimate contact can be used, such as a mixingapparatus featuring an impeller or other structure capable of agitation.Examples of mixing equipment include casing drums, conditioningcylinders or drums, liquid spray apparatus, conical-type blenders,ribbon blenders, mixers available as FKM130, FKM600, FKM1200, FKM2000and FKM3000 from Littleford Day, Inc., Plough Share types of mixercylinders, Hobart mixers, and the like. See also, for example, the typesof methodologies set forth in U.S. Pat. No. 4,148,325 to Solomon et al.;U.S. Pat. No. 6,510,855 to Korte et al.; and 6,834,654 to Williams, eachof which is incorporated herein by reference. In some embodiments, thecomponents forming the composition are prepared such that the mixturethereof may be used in a starch molding process for forming thecomposition. Manners and methods for formulating compositions will beapparent to those skilled in the art. See, for example, the types ofmethodologies set forth in U.S. Pat. No. 4,148,325 to Solomon et al.;U.S. Pat. No. 6,510,855 to Korte et al.; and U.S. Pat. No. 6,834,654 toWilliams, U.S. Pat. No. 4,725,440 to Ridgway et al., and 6,077,524 toBolder et al., each of which is incorporated herein by reference.

In some embodiments, the overall oral product or any component thereofcan be described as a particulate material. As used herein, the term“particulate” refers to a material in the form of a plurality ofindividual particles, some of which can be in the form of an agglomerateof multiple particles, wherein the particles have an average length towidth ratio less than 2:1, such as less than 1.5:1, such as about 1:1.In various embodiments, the particles of a particulate material can bedescribed as substantially spherical or granular. In certainembodiments, either of the first non-tobacco cellulosic material and thesecond non-tobacco cellulosic material can be characterized as aparticulate material. In certain embodiments, only the first non-tobaccocellulosic material can be characterized as a particulate material(e.g., MCC).

In some embodiments, the overall oral product or any component thereofcan be described as a fibrous material. As used herein, the term“fibrous” or “fiber” refers to a material in the form of a plurality offibers, some of which can be in the form of an agglomerate of multiplefibers, wherein the fibers have an average length to width ratio greaterthan 2.5:1, such as greater than 3:1, such as about 3:1 to about 6:1.

The particle size of a particulate or fibrous material may be measuredby sieve analysis. As the skilled person will readily appreciate, sieveanalysis (otherwise known as a gradation test) is a method used tomeasure the particle size distribution of a particulate material.Typically, sieve analysis involves a nested column of sieves whichcomprise screens, preferably in the form of wire mesh cloths. Apre-weighed sample may be introduced into the top or uppermost sieve inthe column, which has the largest screen openings or mesh size (i.e. thelargest pore diameter of the sieve). Each lower sieve in the column hasprogressively smaller screen openings or mesh sizes than the sieveabove. Typically, at the base of the column of sieves is a receiverportion to collect any particles having a particle size smaller than thescreen opening size or mesh size of the bottom or lowermost sieve in thecolumn (which has the smallest screen opening or mesh size).

In some embodiments, the column of sieves may be placed on or in amechanical agitator. The agitator causes the vibration of each of thesieves in the column. The mechanical agitator may be activated for apre-determined period of time in order to ensure that all particles arecollected in the correct sieve. In some embodiments, the column ofsieves is agitated for a period of time from 0.5 minutes to 10 minutes,such as from 1 minute to 10 minutes, such as from 1 minute to 5 minutes,such as for approximately 3 minutes. Once the agitation of the sieves inthe column is complete, the material collected on each sieve is weighed.The weight of each sample on each sieve may then be divided by the totalweight in order to obtain a percentage of the mass retained on eachsieve. As the skilled person will readily appreciate, the screen openingsizes or mesh sizes for each sieve in the column used for sieve analysismay be selected based on the granularity or known maximum/minimumparticle sizes of the sample to be analysed. In some embodiments, acolumn of sieves may be used for sieve analysis, wherein the columncomprises from 2 to 20 sieves, such as from 5 to 15 sieves. In someembodiments, a column of sieves may be used for sieve analysis, whereinthe column comprises 10 sieves. In some embodiments, the largest screenopening or mesh sizes of the sieves used for sieve analysis may be 1000μm, such as 500 μm, such as 400 μm, such as 300 μm.

Configured for Oral Use

Provided herein is a product configured for oral use. The term“configured for oral use” as used herein means that the product isprovided in a form such that during use, saliva in the mouth of the usercauses one or more of the components of the composition (e.g., flavoringagents and/or active ingredients) to pass into the mouth of the user. Incertain embodiments, the product is adapted to deliver components to auser through mucous membranes in the user's mouth, the user's digestivesystem, or both, and, in some instances, said component is an activeingredient (including, but not limited to, for example, a stimulant,vitamin, taste modifier, or combination thereof) that can be absorbedthrough the mucous membranes in the mouth or absorbed through thedigestive tract when the product is used.

Products configured for oral use as described herein may take variousforms, including gels, pastilles, tablets, gums, lozenges, powders, andpouches. Gels can be soft or hard. Certain products configured for oraluse are in the form of pastilles. As used herein, the term “pastille”refers to a dissolvable oral product made by solidifying a liquid or gelcomposition so that the final product is a somewhat hardened solid gel.The rigidity of the gel is highly variable. Certain products of thedisclosure are in the form of solids. Certain products can exhibit, forexample, one or more of the following characteristics: crispy, granular,chewy, syrupy, pasty, fluffy, smooth, and/or creamy. In certainembodiments, the desired textural property can be selected from thegroup consisting of adhesiveness, cohesiveness, density, dryness,fracturability, graininess, gumminess, hardness, heaviness, moistureabsorption, moisture release, mouthcoating, roughness, slipperiness,smoothness, viscosity, wetness, and combinations thereof.

The products comprising the compositions of the present disclosure maybe dissolvable. As used herein, the terms “dissolve,” “dissolving,” and“dissolvable” refer to compositions having aqueous-soluble componentsthat interact with moisture in the oral cavity and enter into solution,thereby causing gradual consumption of the product. According to oneaspect, the dissolvable product is capable of lasting in the user'smouth for a given period of time until it completely dissolves.Dissolution rates can vary over a wide range, from about 1 minute orless to about 60 minutes. For example, fast release compositionstypically dissolve and/or release the active substance in about 2minutes or less, often about 1 minute or less (e.g., about 50 seconds orless, about 40 seconds or less, about 30 seconds or less, or about 20seconds or less). Dissolution can occur by any means, such as melting,mechanical disruption (e.g., chewing), enzymatic or other chemicaldegradation, or by disruption of the interaction between the componentsof the composition. In some embodiments, the product can be meltable asdiscussed, for example, in US Patent App. Pub. No. 2012/0037175 toCantrell et al. In other embodiments, the products do not dissolveduring the product's residence in the user's mouth.

In one embodiment, the product comprising the composition of the presentdisclosure is in the form of a composition disposed within amoisture-permeable container (e.g., a water-permeable pouch). Suchcompositions in the water-permeable pouch format are typically used byplacing one pouch containing the composition in the mouth of a humansubject/user. Generally, the pouch is placed somewhere in the oralcavity of the user, for example under the lips, in the same way as moistsnuff products are generally used. The pouch preferably is not chewed orswallowed. Exposure to saliva then causes some of the components of thecomposition therein (e.g., flavoring agents and/or active ingredients)to pass through e.g., the water-permeable pouch and provide the userwith flavor and satisfaction, and the user is not required to spit outany portion of the composition. After about 10 minutes to about 60minutes, typically about 15 minutes to about 45 minutes, ofuse/enjoyment, substantial amounts of the composition have been absorbedthrough oral mucosa of the human subject, and the pouch may be removedfrom the mouth of the human subject for disposal.

Accordingly, in certain embodiments, the composition as disclosed hereinand any other components noted above are combined within amoisture-permeable packet or pouch that acts as a container for use ofthe composition to provide a pouched product configured for oral use.Certain embodiments of the disclosure will be described with referenceto FIG. 1 of the accompanying drawings, and these described embodimentsinvolve snus-type products having an outer pouch and containing acomposition as described herein. As explained in greater detail below,such embodiments are provided by way of example only, and the pouchedproducts of the present disclosure can include the composition in otherforms. The composition/construction of such packets or pouches, such asthe container pouch 102 in the embodiment illustrated in FIG. 1 , may bevaried. Referring to FIG. 1 , there is shown a first embodiment of apouched product 100. The pouched product 100 includes amoisture-permeable container in the form of a pouch 102, which containsa material 104 comprising a composition as described herein.

Suitable packets, pouches or containers of the type used for themanufacture of smokeless tobacco products may be used for the presentpouched embodiments. Examples of such smokeless tobacco products areavailable under the tradenames CatchDry, Ettan, General, Granit,Goteborgs Rape, Grovsnus White, Metropol Kaktus, Mocca Anis, Mocca Mint,Mocca Wintergreen, Kicks, Probe, Prince, Skruf and TreAnkrare. Thecomposition may be contained in pouches and packaged, in a manner andusing the types of components used for the manufacture of conventionalsnus types of products. The pouch provides a liquid-permeable containerof a type that may be considered to be similar in character to themesh-like type of material that is used for the construction of a teabag. Components of the composition readily diffuse through the pouch andinto the mouth of the user.

Non-limiting examples of suitable types of pouches are set forth in, forexample, U.S. Pat. No. 5,167,244 to Kjerstad and 8,931,493 to Sebastianet al.; as well as US Patent App. Pub. Nos. 2016/0000140 to Sebastian etal.; 2016/0073689 to Sebastian et al.; 2016/0157515 to Chapman et al.;and 2016/0192703 to Sebastian et al., each of which is incorporatedherein by reference. Pouches can be provided as individual pouches, or aplurality of pouches (e.g., 2, 4, 5, 10, 12, 15, 20, 25 or 30 pouches)can be connected or linked together (e.g., in an end-to-end manner) suchthat a single pouch or individual portion can be readily removed for usefrom a one-piece strand or matrix of pouches.

An example pouch may be manufactured from materials, and in such amanner, such that during use by the user, the pouch undergoes acontrolled dispersion or dissolution. Such pouch materials may have theform of a mesh, screen, perforated paper, permeable fabric, or the like.For example, pouch material manufactured from a mesh-like form of ricepaper, or perforated rice paper, may dissolve in the mouth of the user.As a result, the pouch and composition each may undergo completedispersion within the mouth of the user during normal conditions of use,and hence the pouch and composition both may be ingested by the user.Other examples of pouch materials may be manufactured using waterdispersible film forming materials (e.g., binding agents such asalginates, carboxymethylcellulose, xanthan gum, pullulan, and the like),as well as those materials in combination with materials such as groundcellulosics (e.g., fine particle size wood pulp). Preferred pouchmaterials, though water dispersible or dissolvable, may be designed andmanufactured such that under conditions of normal use, a significantamount of the composition contents permeate through the pouch materialprior to the time that the pouch undergoes loss of its physicalintegrity. If desired, flavoring ingredients, disintegration aids, andother desired components, may be incorporated within, or applied to, thepouch material.

The amount of material contained within each product unit, for example,a pouch, may vary. In some embodiments, the weight of the compositionwithin each pouch is at least about 50 mg, for example, from about 50 mgto about 1 gram, from about 100 to 800 about mg, or from about 200 toabout 700 mg. In some smaller embodiments, the weight of the compositionwithin each pouch may be from about 100 to about 300 mg. For a largerembodiment, the weight of the material within each pouch may be fromabout 300 mg to about 700 mg. If desired, other components can becontained within each pouch. For example, at least one flavored strip,piece or sheet of flavored water dispersible or water soluble material(e.g., a breath-freshening edible film type of material) may be disposedwithin each pouch along with or without at least one capsule. Suchstrips or sheets may be folded or crumpled in order to be readilyincorporated within the pouch. See, for example, the types of materialsand technologies set forth in U.S. Pat. No. 6,887,307 to Scott et al.and 6,923,981 to Leung et al.; and The EFSA Journal (2004) 85, 1-32;which are incorporated herein by reference.

In certain embodiments, one or more active ingredients as describedherein are included in the composition within the pouched product, andone or more further active ingredients are disposed in or on theexternal surface of the product (e.g., on or in the pouch material asdisclosed herein). In some embodiments, separate location of the activeingredients may allow differential release profiles (e.g., one activeingredient may be rapidly available to the mouth and/or digestivesystem, and the other active ingredient may be released more graduallywith product use).

A pouched product as described herein can be packaged within anysuitable inner packaging material and/or outer container, such as thoseutilized for smokeless tobacco products. See, for example, the varioustypes of containers for smokeless types of products that are set forthin U.S. Pat. No. 7,014,039 to Henson et al.; U.S. Pat. No. 7,537,110 toKutsch et al.; U.S. Pat. No. 7,584,843 to Kutsch et al.; U.S. Pat. No.8,397,945 to Gelardi et al., D592,956 to Thiellier; D594,154 to Patel etal.; and D625,178 to Bailey et al.; US Pat. Pub. Nos. 2008/0173317 toRobinson et al.; 2009/0014343 to Clark et al.; 2009/0014450 toBjorkholm; 2009/0250360 to Bellamah et al.; 2009/0266837 to Gelardi etal.; 2009/0223989 to Gelardi; 2009/0230003 to Thiellier; 2010/0084424 toGelardi; and 2010/0133140 to Bailey et al; 2010/0264157 to Bailey etal.; and 2011/0168712 to Bailey et al. which are incorporated herein byreference.
